What Lupin the Third adaptations have you seen?

There are five anime series, many theatrical and tv movies and many direct to video movies which are known in Japan as OVAs or Original Video Animations. I have only seen Miyazaki's film, The Castle of Cagliostro and the first episode of the first series. I hope to get into it more later but I've got a lot to watch already. The franchise comes from the Lupin the Third comic by the recently deceased artist Monkey Punch which is based off of the book character Arsene Lupin who is known as 'the gentleman thief'. Lupin the Third is his grandson. I figure that there's somebody on here who knows this franchise better than I do, but I know something that most Lupin the Third fans don't which is that there is also an animated series of the original Lupin character.
